I think the other reviews of this device are pretty much on target. This is an excellent tool and it does what it advertises. But does a tool that basically vibrates fast really need to cost four hundred dollars? Here are my thoughts:
1.) The patent on this tool has expired and there are several multimaster "clones" out there. A short list: Rockwell, Dremel, Harbor Freight Tools, Bosch. Of these, the Bosch is probably the best, and it even takes the Fein blades. However as of this writing you can only buy the uncorded version in the United States. This is not the sort of tool that should be powered by a battery.
2.) All of the attachments work very well. The sanding function is terrific and if you haven't used an oscillator of this type before (for instance if you're used to using a Black & Decker "Mouse" or something similar) you will be pleasantly surprised at this upgrade. The other attachments also work well, but I would not use the E-Blade or any E-Blade to cut metal, unless it is very thin. Don't try to cut hard metals.
3.) I agree that the plastic case inserts are not professional grade. The case itself is acceptable, but I prefer the Bosch cases.
4.) The blades. Buying replacement blades for this tool can be a drag. The Fein blades are of course very good, but at a starting price of $15 and up you're talking about a further outlay of hard earned money. Yes, there are other options, including the Harbor Freight Tools option or making your own blades, but remember these options void your warranty and aren't as good as the Fein blades. BTW, yes you can use round blades with this tool; you don't "need" the star-shaped quick attachment feature that is under the screw, although it obviously helps.
The verdict: if you are a casual user and only plan to do the work this tool requires a few (less than four) times a year, I wouldn't spend the money. Buy a clone tool instead. Of the clones mentioned earlier, I would avoid the Rockwell--the blades don't work with any of the others. Bear in mind that this tool shines best when used for the things shown in the informercial; while you can probably ditch your reciprocating saw after you buy the multimaster, I would still keep around my jigsaw and a few other tools.
In addition, if you are the type of person who has to have the best of the best then I would say that this tool is for you. Sure you can de-grout a bathroom with a dremel or similar tool for about 1/4 the price, but this is surely not the point for somebody like that.
If you are a professional user, in my view this is a no-brainer. Spend the money on as many multimasters as you can afford. They will pay for themselves many times over within a few months.Get more detail about
